Azelastine
Azelastine is a nasal antihistamine. It blocks histamine activity involved in sneezing, congestion and a runny or itchy nose. Both attached products are sprays, but only Astelin contains azelastine by itself.
Key points
- Azelastine blocks histamine in the nasal allergy pathway.
- Astelin is the attached single-ingredient spray.
- Dymista adds fluticasone propionate, a corticosteroid.
- Drowsiness and a bitter taste are recognised azelastine effects.
Astelin keeps the ingredient identity simple
Astelin is recorded as a 10 ml azelastine spray. It connects with allergic and vasomotor rhinitis and appears in both respiratory health and allergy relief.
The spray acts locally in the nose, although some people still experience drowsiness. Official information also notes that alcohol can intensify this effect.
Dymista joins two anti-inflammatory pathways
Dymista contains 137 mcg azelastine with 50 mcg fluticasone propionate. Azelastine blocks histamine, while fluticasone is a nasal corticosteroid that reduces inflammatory signalling. The combination record is attached to allergic rhinitis, not vasomotor rhinitis.
Route also matters here. The catalogue is describing nasal sprays, not azelastine eye drops. Avoiding a route-wide summary keeps the article aligned with the two products actually attached to this entity.
